Hello everyone,
I have a 12V DC load that requires ~500mA. I also have a 3.4V DC source and am about to purchase a Crydom DO061B solid state relay for the input voltage/current and switch, respectively. I'm looking to switch the 3.4V closed (or turn it "on") which activates the relay which in turn turns a light on (the 12V load). In the DO061B datasheet there is a "Max. On-State Voltage Drop @ Rated Current" and my question is does this affect the Input voltage or the Output voltage? For example, does the 3.4V drop to 1.9V at the "-DC CONTROL" leg or does the 12V drop to 10.5V at the "-DC LOAD" leg? I'm going to set this up to have a switch between the input source (3.4V) and "+DC CONTROL", "-DC CONTROL" to ground, 12V to "+DC LOAD" and "-DC LOAD" to the positive terminal of the light. Does anyone have any comments or suggestions? Can anyone answer my question about the "Max. On-State Voltage Drop @ Rated Current"? Thanks a lot!
